The adjusting element 4 can be rotated by inserting a desired one of the engaging

portions

41, 42, 43 into the engaging portion 352, so as to rotate the lower locking body 35, the screw tube 33 and the upper locking body 34 to move up and down until the stoppers at both sides of the adjusting element collide with the convex ring 114 at the side edge of the opening 111 of the lower lid 11.

In the implementation of the invention, when the lifting balance device 2 is lifted, the adjusting device 3 does not work. However, when the lifting balance device 2 is lowered, in order to obtain the optimum required low level, referring to fig. 4 and 5, the third engaging portion 43 is inserted into the engaging portion 352, and the adjusting element 4 is rotated to move the lower locking body 35 and the screw tube 33 upward relative to the screw sleeve 31 until the third stopping portions 431 contact the convex ring body 114; at this time, the upper assembly body 34 is raised to a desired height, and when the elevating balance device 2 is lowered, the bottom of each of the first and

second supports

21 and 22 will contact the upper assembly body 34 to limit the height of the lower position. And the height is the height for providing the needed pillow 1 for the user to sleep on the back.

If the height of the low level adjusted by inserting the third engaging portion 43 into the engaging portion 352 is not suitable for the requirement, the height can be changed by inserting the first engaging portion 41 or the second engaging portion 42 of different sizes and adjusting the height.
